## What it is
firewalld is a dynamically managed firewall daemon for Linux that provides zone-based trust levels for network connections and interfaces, with a D-Bus interface for runtime and permanent configuration. It supports IPv4, IPv6, ethernet bridges, and backends like nftables, iptables, and ipset.

## Use cases
- manage a dynamic firewall on a linux server
- define trust zones for network interfaces
- switch firewall backend between nftables and iptables
- allow applications to add firewall rules via D-Bus
- separate runtime and permanent firewall configuration
- configure ipv4 and ipv6 firewall rules
- set up ipsets for large rule sets

## When to choose
- you run Linux and want zone-based firewall management
- you need a D-Bus API so applications can request firewall changes
- you want runtime changes without losing permanent configuration
- you need support for nftables, iptables, ipset, or ebtables

## When to avoid
- you need a simple static ruleset better managed with nft or iptables directly
- you are on a non-Linux platform
- you need a host-based intrusion detection or IDS rather than packet filtering
